The stock that I bought high

The stock that I bought high was $Tesla (TSLA.US)$ -- yes it is somewhat of a speculative stock. I bought it as part of the "satellite" component, in my core satellite portfolio. When the stock corrected in the past 2 months, I bought a few more shares. However, I won't be buying more, as I don't wish to let the "satellite" component of my portfolio grow too big. This year, most of my allocation is going into index funds and other ETFs like energy and financials.
